Illuminating apparatus

Abstract

Light apparatuses including a light source generating a blue-colored light, a phosphorus filter transforming the blue-colored light into white light, and a light dispersing element receiving the light and projecting a plurality of discrete points of light onto a target surface that have been transformed into white light by the phosphorus filter. Methods for creating a plurality of discrete points of light on a target surface using a light apparatus including a light source and a phosphorus filter and a light dispersing element, including generating a light using the light source, in which the generated light is blue-colored light, transforming the light into white light by passing the light through a phosphorus filter, and causing the light to be incident on the light dispersing element, such that the light dispersing element disperses the light and creates a plurality of individual points of light on the target surface.

AI Technical Summary

Benefits of technology

[0005]Embodiments of the present invention can provide a laser or other light apparatus including at least one light source generating a light having a blue color, and at least one light filter configured such that the blue-colored light passes through this filter thereby producing a white light. In additional embodiments, the light source may be a laser light source or an LED light source. In further embodiments, the blue-colored light may have a wavelength of 450 nm, approximately 450 nm, or 445 nm-455 nm. It will be understood that the expression “blue-colored light” as used herein may refer, collectively and individually, to a light having a blue appearance, to a light having a wavelength of 450 nm, to a light having a wavelength of approximately 450 nm, and to a light having a wavelength of 445 nm-455 nm. In yet further embodiments, the filter may incorporate phosphorus to effect the production of white light from blue-colored light, for example, such that the filter may be a fluorescent phosphorus-coated optical element or a phosphorus-coated film or a phosphorus film. It will be understood that the expression “phosphorus filter” as used herein may refer, collectively and individually, to a filter, film or any other optical element incorporating or made from phosphorus which uses the phosphorus to manipulated blue-colored light to produce white light. It will be understood that the white light need not be perfectly white but rather may approximate white light to within manufacturing and / or acceptable deviation tolerances as may be understood by one of ordinary skill in the art.

Problems solved by technology

However, creating white light for decorative lighting can be difficult in certain circumstances.

For example, creating decorative lighting capable of emitting white light can present difficulties in combining sources to produce the white light while maintaining certain characteristics of the light, such as divergence.
